The pros and cons of the Winix 5510
A summary of our top-level findings after testing this air purifier, following our methodology.
“The 5510 looks good, doesn’t take up too much space, and can clean the air as fast as the Levoit Vital 200S, the Philips 3200 Series and the Smart Air SA600.
So if you’re looking for a mid-sized air purifier that offers excellent air cleaning performance and you value smart features with app support, then the 5510 is definitely worth your consideration.”

Design, controls and app features
A good-looking air purifier with smart features and app connectivity
The body of the 5510 is smaller than that of the now-discontinued 5500-2 and other mid-sized Winix air purifiers.
After reviewing the T810 and now the 5510, it has become obvious to me at this point that Winix is focusing heavily on the aesthetics of their devices with their new generation of air purifiers.
It has a gas sensor that triggers auto mode and a light sensor that puts it to sleep mode when detecting darkness.
The control panel is intuitive and easy to navigate. You also get an air quality indicator in the form of an LED light that changes color (from blue to red) depending on the quality of your air.
Filtration technology
True HEPA filtration with activated carbon and optional bipolar ionization via PlasmaWave.
The 5510 comes with three separate mechanical filtration layers: a removable pre-filter, an activated carbon filter, and a HEPA particle filter.
This means that once the carbon runs out (and starts getting smelly), you can just take it out and keep using the True HEPA filter till you can replace the carbon.
I reached out to Winix for more information and they confirmed that the 5510 comes with 226 grams of carbon – same as the older 5500-2.
As with other Winix devices, the 5510 comes with PlasmaWave, a bipolar ionization process that electrostatically charges particles, making them easier to remove. You can disable it if you prefer to avoid ionizers.
The 5510 uses a different type of filter set, Filter Q — 1712*0123-00, which works with the 5510 and 5520 models but is too small for the 5500-2, the 5300-2 and other older rectangular Winix devices.
Air cleaning performance
We tested the 5510 in our 728 cubic ft. test room, tracking how fast it removed all PM1 particles from the air after we filled the space with incense smoke.
First, we tested the Winix 5510 running at top speed with PlasmaWave enabled. According to our PurpleAir Zen sensor, the 5510 needed 24 minutes to achieve PM1 zero in our 728 cubic ft. test room, which matches what we expected based on its CADR report:
Based on the natural ventilation of our test room, I estimate a top speed PM1 CADR of 249 cfm. This is powerful enough to provide five air changes per hour in large rooms up to 373 sq. ft.
As you can see from the table, the 5510 compares very well against some of the best mid-sized devices we have tested when looking at raw performance at top speed, but considering it is a new model, I was hoping it would be at least a little quicker than the older 5500-2.
our air cleaning tests in isolation won’t tell us the full story…
Sound levels
The sound levels of the Winix 5510 range from 35.2 dBA to 67.2 dBA — considerably quieter than every single large air purifier we have benchmarked it again.
The reality is that if an air purifier is too loud, then someone will turn it off eventually.
That is why I used my sound meter to measure how much noise the Winix 5510 generates from 3 ft. away at each of its fan speeds, including sleep mode:
Be aware that our background noise is 35 dBA, so the 5510 running at speed one (1) and in sleep mode is likely to be quieter if you could measure sound levels in a silent room.
Hitting 67.2 dBA at top speed, it’s louder than many other air purifiers with a similar clean air delivery rate.
At speed 2, it reached PM1 zero in 20 minutes while generating 40.8 dBA, so I repeated the test to see how good its quiet performance is.
Long-term running costs
Running a Winix 5510 will cost you $141.20 per year, combining energy and filter replacement costs.
At its top speed, the 5510 draws 53.84 watts. If you had to leave your 5510 running 24/7, it would cost $61.21 in energy costs for a year.
But let’s look at the other main factor affecting yearly running costs: filter replacements.
According to Winix, you can expect to change filters every 12 months, and you can buy a new filter set for $79.99, so you can expect to spend around $80 each year on filter replacements.
We can now combine energy and filter replacement costs with the list price to calculate how much you will spend on the first year of owning a Winix 5510, and compare this to what you’d pay with other similar performing air purifiers:
The 5510 has a list price of $179.99, but you could find it as low as $149.99 during Prime Day or Black Friday:

Bottom line: Should you get the Winix 5510?
Now that the Winix 5500-2 has been discontinued, the 5510 is the best next thing from Winix.
I hate to say this, but the Winix 5510 offers less powerful air cleaning performance at louder operation than older mid-sized Winix models. Sadly, I can’t recommend the 5500-2 or the 5300-2 anymore, as they have both been discontinued.
But does this mean that the 5510 is a bad investment? Well… not really.
In our air-cleaning performance tests, the Winix 5510 running at top speed is just 1 minute slower than the older 5500-2. And this level of power comes in a much more compact body and smaller filters, which explains why it is louder, as the fan has to work harder.
Plus, the 5510 looks more high-end than the 5500-2 and the 5300-2 AND it comes with smartphone connectivity through the Winix app, which has a good UX and no annoying bugs. So you get some good features that you wouldn’t get access to with the older models.
However, if you are sensitive to sound and prefer to run your air purifier at low, quiet fan speeds, then I suggest you look into the Winix T810. The T810 offers similar performance at top speed to the 5510, but you will get better air cleaning power at quiet fan speeds. Plus, it also comes with smartphone connectivity through the Winix app.
If you are a big fan of app support but are not too bothered about getting a Winix device, then I recommend looking into air purifiers from brands like Levoit and Xiaomi, as their apps are much more polished and feature-rich.
Devices like the Levoit Vital 200S or the Xiaomi Pro 4 will offer air-cleaning performance similar to that of the 5510.
And if you are in the UK or Europe and like what the 5510 has to offer, you’ll be disappointed to hear it’s not available in your region yet.
Two good comparable models would be the Philips 3200 Series (for those who want a smart unit) and the Smart Air SA600 (for those who don’t want smart features).
